Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vehicle exterior surface component, and particularly to a vehicle exterior surface component that is formed by integrating an outer panel and an inner panel, and has an improved water drainage portion.

Among the members forming the vehicle body, external surface forming members such as doors, hoods, trunk lids, tailgates, etc. are formed by overlapping and integrating an outer panel forming an external surface and an inner panel reinforcing the outer panel. For this reason, rainwater and the like enter the inner gap between both panels, which is one of the causes of rust. In order to prevent this, for example, as in the door 1 shown in FIGS. 1 to 3, a drain hole 2 is formed in a predetermined portion A on the lower side of the door 1 to allow water droplets to flow down. Such a drain hole 2 is formed in the peripheral edge 301 of the inner panel 3 of the door 1, and normally, as shown in FIG. It is clamped by the overlapping portion 402 and the folded portion 403 extending from the overlapping portion. In such a conventional structure, a bag-like part C is formed by the overlapping part 402 and the folded part 403 at the lower part of the drain hole 2, and there is a problem in that water collects there and causes rust.

The present invention was devised to solve the above-mentioned problems, and is formed by integrating an outer panel that forms the outer surface of the vehicle body and an inner panel that reinforces this outer panel, and is also formed by integrating the outer panel and the inner panel. In the external surface forming member having an internal space therebetween, a bead portion is formed at a corner of the lower edge of the peripheral edge of the inner panel, and the bead portion extends from the overlapping portion of the outer panel that overlaps with the peripheral edge. The folded portion presses a peripheral edge excluding the bead portion, and the bead portion and a portion of the outer panel facing the bead portion form a passageway that communicates the internal space and external space of the external surface forming member. It is.

According to the present invention, the passage formed by the bead portion and the portion facing the bead portion of the outer panel allows rainwater, etc. that has entered the internal space to be easily removed to the external space without accumulating in the middle, thereby preventing rust from occurring as in the conventional case. Occurrence can be prevented.

The present invention will be described below with reference to the accompanying drawings.

FIG. 4 shows a main part of a door 5 as an external component of a vehicle as an embodiment of the present invention. This door 5 has the same general outline as the door 1 in FIG. 1, and for example, a portion corresponding to the corner D of the lower edge in FIG. Since the same structure as D is formed, only one will be explained hereafter.) is shown enlarged in FIG. The inner panel 6 of the door 5 has a lower edge 601a and a side edge 6.
A peripheral edge portion 601 made of 01b is bent into a stepped shape with respect to an intermediate step portion 602. However, the lower edge 6
At the corner between 01a and the side edge 601b, a bead portion 7 having a substantially U-shaped cross section and continuous with the intermediate step portion 602 and having a width h (in the door thickness direction H) is formed. Outer panel 8 forms an external surface 801 . This outer surface forms an overlapping portion 802 on its periphery that overlaps with the peripheral edge portion 601 . This overlapping portion 802 extends from this and cooperates with a folded portion 803 that is folded back to clamp the peripheral edge portion 601. In this case, the lower edge 601a is sandwiched between the overlapping part 802 and the folded part 803 by a hemming machine (not shown) and pressurized at the same time. Similarly, the lower edge 601b is connected to the overlapping portion 8
02 and the folded portion 803 sandwich and apply pressure at the same time. Thereafter, the corner between both folded parts 803 is subjected to pressure treatment with the bead part 7 removed, and a substantially dogleg-shaped corner folded part 804 having a relatively small width is formed. Through these processing treatments, a passage 9 having a width h can be formed between the bead portion 7 and the overlapping portion 802. This passage 9 communicates an internal space 10 between both the outer and inner panels with an opening 11 facing the corner folded portion 804. Moreover, the opening 11 is oriented diagonally downward, so that water droplets on the inner space 10 side can be guided to the opening 11 and easily removed.

In this way, the door 5 shown in FIG.
can be formed. As a result, the interior space 10 of the door 5
It can help eliminate water droplets and prevent the occurrence of rust on various parts of the door. Moreover, the process of forming the drain hole (see FIG. 2) 2 on the inner panel 6 by piercing processing is naturally unnecessary, and the processing can be simplified.

In the above, the door has been explained as an external component of the vehicle body, but it is not limited to this. For example, the door may be used as a trunk lid (not shown) or the corner D of the lower edge of the tailgate 11 shown in FIG. Each corner F of the hood 12 shown in FIG.
A similar effect can be obtained by forming a bead portion and a portion facing the bead portion of the outer panel similar to those explained in the drawings to form a passage.
